    Default AC/Heater Controls

    I've got an 04 Silverado Z-71. It's got the digital climate control and the knob on the driver's side is really acting up. It takes me pushing and pulling on the spin part of the knob with alot of spins to get it to where I need it.

    I pulled the unit out and got the part number off of it...part #15107733. I've looked and come across units that look the same but have different part numbers.

    Does anyone know if the ac/heater controls are basically the same with different part numbers for different vehicles (Tahoe/Silverado, etc.) or if they are different based on package deals (LT, etc)?

    Any help would be greatly appreciated.

    Alan-

    I'm sorry to hear about your climate control problems. I've never owned that particular vehicle or come across that problem before so I can't give you any direct advice. In general, when it comes to part numbers, I would tend to err on the side of caution. When I bought the Suburban I had issues with my climate control as well. It would only work in the OFF position and putting it 1,2, 3 or 4 would turn the fan off.

    It turned out that someone had replaced the controller module with one that was not identical - it was missing the button for the rear defrost. Now, as to if it worked before with that module in there, I don't know. I just know it wasn't working for me at all.

    But hopefully if anyone here can help they'll chime up and let you know.

    Good luck!

    Steven,

    Thanks for the info. I've seen alot of the controls but with many different part numbers. They all look the same though so I don't wanna get the wrong one. The best piece of info I've seen so far was a replacement from a website and it listed the number for the control that I have along with 2 other ones (out of a total of 13) I've seen.

    I guess the best thing for me to do is call my dealership here and ask the parts manager about it and what numbers are basically the same.

    I think that would be best as well. If, for nothing else, just to educate yourself on what the different part numbers are for. They may just be same part for different trucks... may be all interchangeable but best to ask. If/when you find out make sure to come back and let us know so the information can help the next guy with the same question!

    Good luck!

    Here's what I found out today about the A/C Controls:

    Part #15107730 was started in Jan 2004.
    Part #15137655 replaced Part #15107730 starting in August 2004.
    Part #10367042 replaced Part #15137655 in May 2005 and is the most recent climate control.

    They will all 3 work in the truck so they are interchangable.
